A battery, comprising:
- a negative electrode sheet including a negative electrode part coated with a negative electrode active material and a first uncoated part disposed adjacent to the negative electrode part;
- a positive electrode sheet facing the negative electrode sheet and including a positive electrode part coated with a positive electrode active material and a second uncoated part disposed adjacent to the positive electrode part;
- and
- at least one partitioning film disposed on a surface of the negative electrode sheet or a surface of the positive electrode sheet,
- wherein the positive electrode sheet, the negative electrode sheet, and the partitioning film include a roll shape formed by wrapping, and
- wherein at least a portion of the first uncoated part of the negative electrode sheet or the second uncoated part of the positive electrode sheet includes at least one internally recessed notch structure.
